设计了一种新型超磁致伸缩泵结构,结合其结构特点,建立了超磁致伸缩泵动力学仿真模型,并在MATLAB环境下进行了仿真研究。为了探索流体阻尼对超磁致伸缩泵流场分布的影响,建立了超磁致伸缩泵流场流固耦合仿真模型,并对泵腔高度、进出管位置、进出管直径以及倒角形状进行了仿真分析,得到了流场结构对泵性能的影响规律,为超磁致伸缩泵流场分析提供依据。

A new type of giant magnetostrictive pump(GMP)is designed.Combined with its structural characteristics,the dynamic simulation model of the giant magnetostrictive pump is established and its simulation is carried out in the MATLAB environment.In order to explore the effect of fluid damping on the flow field distribution of the giant magnetostrictive pump,a fluid-solid coupling model of the giant magnetostrictive pump flow field was established.Then the pump cavity height,the inlet and outlet position,the diameter of the inlet and outlet and the chamfer shape is simulated and analyzed,and the influence of flow field structure on pump performance is obtained,which provides the basis for the analysis of flow field of giant magnetostrictive pump.
